This invention `relates generally to power driven scissors adapted foruse by barbers,

the invention having more particular reference to a novel type of powerdriven scissors which will act more efhciently.

The invention has for an object the provi.

sion of an improved power driven scissors of novel construction andarrangement of scription and accompanying drawings, andl to the appended'claims 1n which the various novel features of the invention are moreparticularly set forth. i y

vFig. 1 of the drawings, isa front elevat-ional view of vmyimprovedpower driven scissors. A f' Fig. 2 is a similar view, showingthe cover removed so as to expose certain working parts.

Fig, 3 is a longitudinal sectional view taken on the line 3-3 of Fig. 2.

As here embodied my improved power driven scissors comprises a case 10,havingl an extended handle element 11, of hollow construction, andhaving a cover 12'with a detached to the case 10, as at-.14,by screws,Vbolts or the like. 'The handle ca-p 15, is provided with a flangedelement 16, adapted to engage a recess 17,fformed in the ends of thehandle elements 11 and 13, and is removably attached thereto, by screws,bolts, or the like.

The tubular member 18, is rotatively mounted in the bea-ring 19 providedin the handle element 11, and has formed or cut in its lower extremity anotch 20, adapted to engage the extended element 21, of the drivingmember 22, attached to the flexible member 23, extended through anaperture formed in the end of the handle elements 11 and 13, and in thehandle cap 15, the flexible member 23 has attached at its extendedextremity, a suitable connection, as a means of connecting same to anelectric motor, or vany suitable primeV mover, so as to rotate thetubular member 18, the latter described elements not being shown in theaccompanying drawings.

The pinion 24 is attached to the tubular member 18 and meshes with agear 25v attached to the jack shaft 26, so as to rotate the jack shaft26. The pinion 27, and the gear 28 are attached to thejack shaft 26,rotatively mounted in the kbearings 29 provided in the handle e-lement11, and are adapted pending handle element 13, removably at? tobeslidably engaged by the gear 30 and thev pinion 31,respectively,attached tothe tubular member 32, slidably mounted on theshaft 33, thetubular member 32 is'provided with an inward dependingmember`34, afpin or the like, adapted to engage in an elongated' slot 35formed or cut in the shaft 33, soy as tovper mit the said tubular memberv32 to rotatethe shaft 33. The above described construction being suchas rwill permit the shaft 33t0- be rotated at two-different speeds;`

The shaft 33'is rotatively mounted in the bearing 36 provided-in thehandle element 11,` and is rotatively engaged in the'tubular mem-'- ber18. vThe lever k37 or trigger,is positioned outside the cover 12, andis-attached to the v screwv 38, pivotally kmounted inthe cover 12,

and has attached theretov a disc v39,"pi-ovide'd with a pin 40, attachedthereto, at or near its periphery, and extended therefrom, adapted toengage in anelongated aperture41,`formed or cut in the slidable memberv42pr'ovided with an elongated aperture 43, as a means of slidablyattachingthe slidable member 42, by the screw 44 to the' inside of thecover 12. The leaf vspring 4 5, is attached, at one extremity to thescrew 44,l and isprovided with a' bent free extremity, adapted to holdthejslid- 'able member 42 i-n any Ydesired position. The slidable member42.y is provided withV a fork shaped extremity 45 adapted to engage inthe axial groove 46 formedv or cut in the tubular member 32. The abovedescribed. construction being such yas will permit the level 137 whenpivoted to slidethe tubular member 32 .so as to' rotate the shaft 33 attwo different speeds. y

rfhe bevel pinion 47 is attached to the shaft 33, and meshes with abevel gear 48, rotatively mounted on the pin 49, attached to the case10. The lever 50, is attached to the bevel gear 48, and has pivotallyattached at its free extremity, a link member 51, pivotally attached tothelever 52, pivotally attached to the pin 53, attached -to the case 10.The movable scissor blade membor54, is pivotally attached to the pin 53,and is provided with a cutting edge 55, extended outside the case 10,and is provided with an extended element 56, located inside the case 10,having formed or out therein Va notch 57, adapted to receive theextended member 58of the lever 52. The above described constructionbeing such as will permit the bevel gear 48 when rotated to close themovable scissor blade member 54 in shear# ing contact with the fixedscissor blade member 59, so as to cut hair, as may be desired. The fixedscissor blade member 59 is extendedioutside the case 10, and isprovidedwith a cutting edge 60, and is attached to the pin '53, and isprovided with an extended element 61, located inside the case 10, and isattached as at 62, by a screw or the like to the case 10. The spring 63,is attached at one extremity to the extended element 61 of the fixedscissor blade member 59, and is wound around the pin 53, and isattached, at its other extremity to the extended element 56 of themovable scissor blade 'member 54, so as to open the said movable scissorblade member 54, when the bevel gear 48 is rotated, as is required whencutting hair.

- `The lever 64, or trigger, is positioned outside the lcover 12, and isattached to the screw 65,- pivotally mounted in the cover 12, and hasattached thereto a pinion 66, located inside the cover 12, meshing witha pinion-67 attached to the lever68, pivotally attached to the pin 69,and provided with an extended element 70 located at its free extremity,adapted to engage in a notch 71 formed or cut in the extended element56`of the movable scissor blade member 54, so as to limit the amountl ofopening of the movable scissor blade member 54.

While I have above described the preferred form', constructionandarrangement of the several elements employed, it will be understood thatthe device is, nevertheless, susceptible of considerable modificationtherein, and

`I-therefore reserve the privilege of resorting to all such changes asmay be fairly embodied within the spirit .and scope of the invention asclaimed.

I-Iaving thus described my invention, what I claim as new and desire toprotect by Iletters Patent of the United States is as follows:

1. In a power driven scissors of the class described, adapted for use bybarbers, a bevel pinion attached to a shaft, said bevel' pinion meshingwith a gear rotatively mounted on a pin, a lever attached to the saidbevel gear, a link member pivotally attached to the free extremity ofthe said lever, said link member pivotally attached to a second leverpivotally attached to a pin, a movable scissor blade member pivotallyattached to the said pin, said movable scissor blade member providedwith a cutting edge, and provided kwith an extended element havingformed therein a notch adapted to receive the extended member of thesaid second lever, so as to close the said movable scissor blade memberin shearing contact with a fixed scissor blade member, as a means ofcutting hair.

2. In a power driven scissors of the classk described, adapted for useby barbers, a fixed scissor blade member provided with a cutting edge,said fixed scissor blade member attached to a pin, and provided with anextended element, a spring attached to the said extended element andwound around they said pin, and attached to the extended element of amovable scissor blade member, so as to open the said movable scissorblade member, said spring working in co-operation with the pivoting ofthe said movable scissor blade member.

3. In a power driven scissors of the class described, adapted for use bybarbers, a lever attached to a screwpivotally mounted in a cover, apinion attached thereto, and meshing with a second pinion attached to alever, plvotally attached to a pin, said lever provided with an extendedelement located at its free extremity, adapted to engage in Va notchformed in the extended element of a movable scissor blade member so asto limit the amount of opening of the said movable scissor blade member.

In testimony whereof I have vaflixed my signature.
